Leaking From Bottom of the Machine

If your Profitec Pro 800 is leaking from the bottom of the machine, there could be several causes. Refer to the guide below to diagnose and repair the leak.

  1. Check the water tank and drip tray to make sure there are no cracks or breaks where water can escape. Make sure they are properly positioned on the machine.
  2. Open the machine and check all of the connections to make sure they are securely attached.
    • Examine the pump and boiler assemblies to see if there are any cracks in them. If the machine was exposed to sub-freezing conditions without being properly drained it can cause these components to crack. These parts will need to be replaced if they are cracked.
    • Make sure both the inlet line and the outlet line on the pump are securely connected.
    • Check the various valves located on top of the boiler assembly.
    • If water is leaking from the relief valves, then the boiler may be overfilling. Distilled, reverse osmosis, and zero water are not compatible with this style of machine as the water level probe depends on minerals in the water to detect its presence. These water types do not contain minerals, and so the machine will continuously fill until it overflows, usually resulting in water leaking from the relief valves.
    • If water is leaking from the relief valves even though you are using water that contains minerals, then you may need to clean the water level probe.
  3. If the machine is plumbed, then there may be too much pressure at the inlet line. The pressure restrictor may need to be adjusted, or if you do not have a pressure restrictor installed you may need to install one.
  4. If the valves are leaking directly from where they screw into the boiler, then they may have a broken seal. Try resealing the valves by using white teflon plumbers tape or food safe permabond and screwing them back into the boiler.
  5. If there are any broken or cracked hoses, or hoses with pinhole leaks, they will need to be replaced.
  6. If you cannot find the source of the leak, it's possible the water you are seeing is from water spilled when refilling the machine, or from the drip tray being out of position. It is also possible to run the unit with the casing off to help identify the source of the leak; precautions should be taken to protect yourself from any exposed wiring or hot water or steam that comes from the machine if you attempt this.
